One thing that I have been particularly grateful for from my previous job is the experience of traveling. Although, I only spent 2 months of 2012 in my own bed (yes, less than 60 days at home!), every experience becomes my sole property.
Everything you do right now and have done in the past, not only defines you, but eternally gives you the strength you need to become who you’re meant to be. The pain, the happiness, the joy, the misfortune, the suffering are all part of you.
Simplistically, what ever doesn’t kill you makes you stronger. You live, you love, you grow.
