Don't do it, it will not end up being worth it. Instead make some time on the weekends to learn and build what you want. Maybe wake up earlier and spend an hour each morning on something you want to do. Experiment with your productivity outside of work and try to get things done that way instead of cashing out your 401k and setting your finances back several years.
