Lots of good advice, hope something clicks for you. Only thing I will add was that really pushing my knees out hard kept me from leaning so much. I still do sometimes when my back gets too tired to stay tight, but it helped overall.
Keep working hard and being smart. You'll get where you want to go.

Hack away at anything which isn't essential. Do what you love, and do it often. Fazc.
Everything competes for recovery so more assistance is not always the best idea. miked96
