I would appreciate the comments from active traders more because it would give a proper insight on how it would look like if I finally make my way into the trading or the investing world and just need to keep focus.
Your hobbies do not have to change just because you started trading. The hobbies that you have and things that you love doing before you started trading can also be the things that you do while you trade provided that it does not threaten to take away or tamper with the capital meant for trading and does not get you overly distracted that you begin to lose in trades.
What do they do as a hobby that keeps them focused on their task?
Do they see movies while trading and waiting for an outcome or do something else during the time?
If you enjoy painting as a hobby, you could be paiting on your canvas while waiting, if you enjoy video games, you could be play a game or two while waiting. If you enjoy anime's you could watch some episodes or scenes while waiting. If you enjoy music, you could play a song, or an album while waiting. The choice of what to do should depend on what you already like. I don't think there are fixed or specific things that traders should do while waiting.
