Balancing chess and work I started chess 2 years ago at 500 ELO and have climbed up to 1900 ELO (chess.co) recently. I have fallen deeply in love with the game and have made it a life goal to achieve eventually a mastery title.
Unfortunately, I started chess very late (20 years old), an age where one usually is in university and starts or has started working. Very soon I will have to move to my apartment, work full time, cook food, etc. I fear I will not have enough time as I currently do to dedicate my self sufficiently to chess; a lot of time is required to improve in chess. I was wondering how does one balance chess serious improvement and work/life responsibilities ?
In conjunction with this question, what would you consider an optimal training time regime? Is 1 hour a day sufficient time to gradually improve, or will that be pointless?
20 years old is not that late to start.  Any amount of time spent can help improve or maintain skills.  Consider how much time you would like to spend and commit to it.  Adjust to ensure you are enjoying your chess time.  Easy to improve when having fun. An hour a day is fine to start.
How you spend you time is also important.  There is much good advice on this site, for example this
You will not get a title playing on chess.com.  Consider playing in tournaments that lead to titles.  Probably your rating will be different then chess.com so that will give you a better idea how close you are to your goal.
I learned to play when I was 7, but in my teens I did not have anyone better than me to play so I could not improve.  Once I started university it was easy to find folks better than me and I started playing and studying chess much more.  Most of my chess improvement was during university.
