Poker What's your advice on rebuys?

So since Feb 21, I've managed to tally tournament cashes of $4149, a lil over $3,000 and a lil over $6100, both the 4149 and<6gs score supplanted my best cash which was a lil over 4gs on full tilts Midnight Madness back in the day.. my question is what's your viewpoint on rebus in tourneys? I've found myself rebuking in $20-$35 a couple times if need be(the 3k score was actually a $30+3 6k gtd and the 4k score was a 5th place in a $150 with 1 rebuy.. I've found the little more expensive tourneys have been a lil easier, as it's a grind, reach the money then really its a free frail so to speak where aggressiveness (c betting, 3 betting but not calling off witout premium hands or a chip adv etc) is key.. after making a lil over 10 gs profit in 3 weeks, just lost a lil over a G within 2 days.. wha should be the mindset, still play the bigger buyin tourneys and don't rebuild, atleast more than once?

You mention several times that you rebuy in $20-35 tournaments, and also in a $150 rebuy. On the one hand, the rebuy option is something that can offer a strategic advantage, especially if you have the opportunity to buy more chips to continue playing aggressively and maximize your earning potential. But on the other hand, it can also increase variance and lead to greater losses in the short term.
Always keep an eye on your bankroll management. If you're playing with higher buy-ins, this becomes even more crucial. Many poker players recommend investing no more than 5-10% of your total bankroll in a single tournament, and even less in rebuys. This minimizes the risk of a series of losses that could affect your financial stability.
