I really liked this post because its honest and sincere, but my opinion is, don't power down yet, give back to the community the way you have been and save it up until you are 100% sure you want to do it. if you are still debating wether to do it or not, then its probably not the right time, you will know when it is, when you wake up one morning and say.... fuck this I'm powering down now.. LOL
