If you can learn to execute entries and exits by removing emotions you will become dangerously good and confident in your ability.

Some suggestions to get there:

Get outside of your comfort zone by trading with small amounts first. Alternatively, a suggestion I always offer to clients in GTG is actually 'paper trading', whereby you can use 'not real money' on a platform or you manually track trades in a journal and write the success/failures along the way.

Learn: there are 1000s of ways to trade, different strategies, different markets, different chains, some passive, some active, different timeframes etc. Furthermore, learning gives you new knowledge, new experiences and this helps build a better wall with emotional trading.

There is no one way to trade. Too many people see success in one way and think thats the only way to 'make it'. That couldn't be further from the truth.

Be prepared to fail and make mistakes. Trading is about probabilities and risk: ideally you are increasing the probability of your success and minimising risk. No trader wins 100% of the time.

However, if losing starts to stack, definitely stop and re-establish your strategies and processes.

Keep it as autonomous as possible: allocate % per trade, if you're using leverage, start low; if you're trading Memecoins or NFTs, don't over allocate into one trade.

Always have liquidity / cash / fiat / stables available. If you don't, take some profit or cut weak trades.

Trading is a journey that is ever evolving, but theres things you can do, like the above that can help you become a far better trader who is far less emotional.
