Gambled Bitcoin away

How do you cope with the regret of losing Bitcoin over the years through trading or gambling, especially knowing how much it could be worth now? I understand the right approach is to focus on moving forward and continue stacking, but it’s hard not to feel the pain, especially when I knew about it before most people but got too greedy and lost a significant amount by trading. For all the Bitcoiners out there, how do you deal with the weight of past mistakes and move on?
