It is possible. You just have to do the work a little at a time. I've been doing this work a long time, on and off. Got lost in addictions a little here and a little there. Got clean, went back, got clean, went back. Took some time off, but for the last six years, I have done nothing but work on myself, and I've missed out on a lot of good times and fun, but it was all bullshit because it would have been pretending anyway.
