Most often i don't blame people who come into trading with out a second or actual source of income or plans for contingencies because they come inmost often with the mindset that they are going to make a quick rich life from trading so they go all in at once and worse is for those who gets to get beginners luck at their first trial so they get fooled into thinking it is actually that easy only for them to later discover they needed to do even more for them to be bale to consistently reproduce such results which they had at their first set of attempts.
it is very important you have a source of income as a beginner trader from which you are going to fund your trading dreams before the trading will later fund the life for you after you must have mastered the act of trading and you are now a master at it. Trading i always tell people is not a get rich quick scheme so stop looking at the influencers who are showing off results of years of hard work, they will only tell you the best they can tell you but can not give you the actual experience, you may have to get it by yourself, it takes time and nothing good comes easy, you will need time to build it. Trading takes time to master and become profitable but you can master it if you put your mind to it and put in the work.
For a beginner or professional, having another source of income is very important. Sometimes this trading is a thing that is not the way we think it is; that is, many professional traders put their money into something else apart from trading so they will have multiple sources of income, as they will be generating money from trading and also another source. If not, to some extent, it is seriously not advisable to depend on only trading.
However, as for beginner traders, having a source of income is very important because you, as a beginner that is trying to level up in trading, are expected to use just a small amount of money to trade due to the level of understanding, and you can see that things will go smoothly because even if you lose the money, you still have another source to make things work out. But a beginner who does not have another source may end up in debt because the market did not favour him or her.
