Bitcoin will always be just a side income to me and I will never ever quit my day job. I can see a big future with bitcoin but it will still my only source of extra income. I'll earn more with my job today + earning bitcoin online,and that makes me happy onmy daily life.
Good for you at least you are clear with your plan, but that would not mean that it is your plan until the end as time will come that you will realize how badly you need money and you cannot get all the money you need in doing your job alone, we have plans to be comfortable in the future so invest if you have time.
And for sure in the future you are going to have to set your priorities and if you are going to earn better with your day job for sure you are still going to work part time with bitcoin. We must be wise on how we are going to take our decisions, because this kind of situation is really going to feel you better forever or worst.
