Hey Doron great initiative. First of all I think this 3 yr programme will be a good start especially if you feel wholeheartedly its something you want to do. Notably, programmers are in high demand and are well paid. You are helping converge supply and demand :)
Regarding
how do you handle that fear and how do you persevere into seeing something through to the end?
Well here I think that you'll probably find hard subjects and perhaps boring, but I would persevere mainly for having paid for it, but also for a personal conviction of finishing what I have started.

Thank you for your advice and motivational words. The fact that programmers are in demand really helps me to make this a great argument to persevere.
