Would you study hand histories more than videos? I've studied so many videos it just seems that its becoming repetitive. But there is a lot to learn from coaches thoughts in certain spots. So not sure which one would be more beneficial?
Personnaly, I think that there are personal factors in choosing how to learn poker. Some learn better by listening videos, other by reading / analysing HH. At some point, I agree that videos seems repetitive, but I always find at least a couple of spots that help me fine tune my game. Also, I am a FR player, but I started to listen to some 6 max vids and I figured very interesting things by doing that and learned a lot at the same time.
All in all, I like to listen to a couple of good videos every week and discussing 2-3 hand histories each day I am available for poker. Coaching is another good complement that I use as well and that helps me as well.
In anyway, I think that, like Blah said, you need to want to improve badly! I mean listening to a vid is one thing, but if you don't take the time to get the idea of why the coach is taking this line or this line you will waste your time. Same for HH. As for coaching, your coach will help you and guide you, but you need to prepare for your session, take note and do your homeworks outside the class! As we don't have much time as part time player, make sure you don't waste any of this precious time!
In short, there is no shortcut, hard work will payoff in the long run. With a full time job, if you want to succeed, you need manage your schedule very well and put a high priority on poker in your free time.
Personnaly, I always find some time to study every week and play decent volume (easier now with Zoom) every month, despite having a full time job and playing softball 3 nights a week! I don't have kids yet and it might be challenging to continue, but I guess there are solutions on how to manage a schedule accordingly. Poker is a decent side income for me and I think this is possible if you are dedicated enough.
