can i sustain my current lifestyle? (workaholic)

[ozdg3nr8]

i guess im posting this because i have started struggling a bit mentally getting a bit depressed and wondering if its all worth it.
i work in a family business which takes up around 50 hours a week of my time which is fine, im used to these hours, i have been doing this since i was 18, i am now 24.
For the past 2 years i have played "semi-professional" poker in my spare time (15-20 hours) a week. In this current year to date i have made 90k tax-free (australia) from playing poker alone. It has become a real drag on me to play, i essentially hate playing but i "need" to for personal reason/goals.
I wish to achieve complete financial freedom by age 35 and think i am on track to make this goal a reality if i sustain my current lifestyle which is work, eat, [censored], play poker repeat.
Currently, i have around a 300k in liquid assets (cash, stocks) and am paying off a 2 million dollar mortgage which is joint owned by my brother who works even harder than i do, but he is far older (33).
the mortgage shouldnt be a problem as our family businesses are fairly sucessful.
i guess only i can know if i can sustain this lifestyle, many of my friends say i am insane for doing what i do, i however think that only great things are achieved through very hard work.
i guess my mentality is to achieve the goal at all costs, i have no balance in my life, everything revolves around making money, although i do not live a balla lifestyle i have almost everything i want in terms of toys and such.
i guess im just rambling now, maybe i need a motivational kick to keep me going.
