played 41-42 years lol 17 online super tough danny NG gave me advice maybe in 2007-2008 range to have a full life do not solely revolve life on the game see family take breaks holidays etc.. win reward self etc...
best advice i have ever received i do take a break almost yearly to recharge batteries etc... and do take time off every week a day or whatever....
im older now so sometimes its needed
key is this you want to be at your best sharpest as when it mattes the most

so act accordingly for those times preparing yourself however you need to

by a break by an ice cream ? doesnt matter.....
if your winning but cant stay awake yep you should sleep this is hardest one for sure.... sooner or later you will make a bad move and cost yourself imho
one thing though push as long as you can winstreaks dont always happen all the time
