  Apakah layak sebagai seorang manusia memakan harta saudaranya sendiri, apakah kita benar benar membutuhkan ataukah hanya sekedar pelampiaasan dari kegagalan yang kita alami. Jika kita tidak mendapatkan apa yang kita inginkan selama ini, bukan kemudian kita menghalalkan segala cara untuk mendapatkan sesuatu yang dapat meringankan beban kehidupan. Biarlah semua sudah tertakar, jika diri kita merasa tidak mampu maka pencipta pun akan ikut mewujudkannya, padahal sejatinya kita mampu dan lebih dari cukup untuk bisa melaksanakanya sampai selesai. Andaikata pun ditengah jalan ada hal terjadi yang dalam kehidupan sehingga membuat kita menjadi tidak mampu lagi untuk menopang beban kehidupan itu, maka itupun sudah menjadi jalan hidup yang menimpanya, percayalah bawhasanya tuhan adalah pengatur kehidupan terbaik bagi ciptaanya. Jangan pernah kita memakan harta yang bukan hak kita, itu hanya akan mengotori hati kita dan menjauhkan diri kita dari tuhan. Tuhan tahu apa yang terbaik untuk kita,...

Aku merasa sangat berterima kasih atas kesempatan yang telah diberikan, sehingga aku dapat mengenal kehidupan perkantoran di head office pusat kota Jakarta.hal ini tidak mengurangi semangatku untuk terus berkarya, memberikan karya-karya terbaik melalui pemikiran, ide-ide kreatif yang kemudian kuubah menjadi sebuah seni yang bisa dinikmati oleh banyak orang. Jalanan kota Jakarta setiap pagi dan sore selalu macet, terkecuali di hari sabtu dan minggu yang akan Nampak sedikit lengang. Seharusnya setiap hari aku bisa membuat berbagai karya, tidak hanya monoton dengan pekerjaan, dulu katanya pekerjaan itu akan selalu ada dan tidak ada habisnya, jadi sudah seharusnya kita usahakan untuk tetap bisa menikmati apa yang kita kerjakan. Pada dasarnya manusia normal akan selalu merasa tidak puas akan semua hal yang sudah ia dapatkan, dan itu men...

  Seorang lelaki sejati tak pernah menyesali keputusan yang dia ambil, sekali perahu dikayuh ke tengah dia akan tetap berlayar walaupun belum tentu ia akan bisa pulang kembali dengan selamat. Namun dia yakin akan berusaha sekuat tenaga untuk mencapai apa yang dia mau. Setiap pilihan kehidupan selalu memiliki konsekuensinya, terlepas dari pilihan baik ataupun buruk di dalamnya akan memberikan sebuah pengalaman yang akan berguna untuk dirinya sendiri ataupun untuk orang lain. Tentu setiap orang menginginkan pilihan terbaik dalam hidupnya, namun kehidupan tidak selalu memberikan apa yang kita mau, kehidupan selalu memberikan tantangan kepada setiap orang, tantangan yang ada akan memberikan kebahagiaan tersendiri disaat kita dapat menyelesaikanya. Tak ubahnya dalam hidup, proses pembelajaran berlangsung secara terus menerus selama kita masih bernafas. Bagi seorang anak laki-laki dia memegang peranan yang teramat krusial di dalam hidunya, sebelum dia berkeluarga dia bertanggung jawab ...

       Aku anak pertama yang bercita-cita untuk sukses. Jadi kebanggaan orang tua,mengangkat derajat orang tua, memiliki 5 cabang usaha yang aku dirikan dengan jerih payahku. Bebas finansial, banyak hari aku jalani dengan tegukan secangkir teh, kopi dan rokok sembari menikmati kicauan burung peliharaan dan ikan di akuarium megahku. Rumahku yang sederhana dan nyaman, cabang-cabang restoran yang selalu ramai pengunjung. Itulah impianku.      Kembali lagi ke waktu sekarang, dimana sore ini udara terasa dingin cuaca mendung di depan teras sebuah kamar kos beralaskan kursi plastik aku duduk membongkar imajinasi yang berada di otaku.

  The Art of Minimalism Life All of us sure have things that ever use every day or just make ourselves happier when we have time flies Does this thing feel didn’t any special. I rewrite the opinion from Fumio Sasaki about how to impact from minimalism of life. Having things that we use only, not too much, simply will make us happier long last than before. Not to adjust absolute concept ideal happy Our public has some standard ‘sample happier that shows a way of life ideal, like getting work permanently, married, having a family, having two or three children then enjoying continuing old age with grandchildren. That standard picture accepts a wide range in our country as happy life and much more from our journey and spot in us of life sure happy if all of that already reach. That’s the wrong concept! Positive psychology, a branch of physiology that learns about feeling satisfied and self-fulfilment shows different concepts and models for a happy life . Sonja Lyubomirsky, 50...

This time I work after returning from my town in Klaten Central Java, unfortunately, I feel that working as a worker on the site more has benefits than in the office, especially in the Head Office. On-site, we get 2 weeks off in every 8 weeks of work and all facilities like eating, laundry, and ticketing are already served by the company, on the other hand, if we work in the head office, we only get a holiday twice every week and red calendar/holiday together although we can live together with our family every day. I hope from this I can finish my home, so I can decide to prefer easy to continue at another company, I will try again the company of mining that sees workers at to job site. On this day age is 29 th years old and one month again becomes 30 th years old it’s not easy for many people in Indonesia. I have one brother that in this year will continue to study at university, but at this time when I wrote this, he didn’t get into the university with the major that he wanted, I a...
