Everyone is different, and every situation is special. So, what might work for one person might not work the same for another, and it might not work all the time either. Here are some tips to help you set aside your emotions and stay focus on your trading stratgy.

Make a plan and follow rules you set without breaking them.
Only invest in things you understand and believe in.
Always do your own research and think carefully.
Think about how much you could gain compared to what you could lose.
Try meditation and mindfulness to stay calm.
Only invest money you can afford to lose.
Keep a journal of your trades and feelings, so you can learn from them.
Take breaks when needed.
Find other good things to do like reading, being outside, or spending time with loved ones.
Notice if your actions are causing stress and talk to someone you trust if you're having problems.

Hope this helps!
