I wonder if i resign now, what kind of job should i look for next? what other opportunities and challenges await me?

Time to make decisions again. It's a chore, but every time i want to make a decision regarding my life, i feel motivating.

Some time in the past, i learned not to regret on the decisions I've make. Even if it's probably wrong. Move on with the decisions you make. But make sure you are sure of the road in front of you. 'Cos you control your own life. =)
