You have been practicing 2-3 hours each day for the last +15 years? Wow.
bows in front of you
At the moment I manage to practice ~2 hours starting somewhere between 10 or 11 p. m.
Problem is, I’m awake as a lit candle when I go to bed and tired as fuck when I get up. But it’s working. Big leap of improvement over the last few months.
When do you see/spend time with your daughter?
Does she ride the bike with you? 
I wish I would have practiced that much over that period of time…
