Having another job is very important because we will be able to earn money. So when we are in long term investments also have productive money from other jobs.
This is necessary for every long term holder, a job or a business that would generate an income for finance your daily expenses in life.
You can't force the market, it requires timing and long term hold does not have a specific number of months where we can sell and enjoy our profit, sometimes it will end us a loss or if not, it would make us wait for more than a year like those who invested in 2017 that until now they cannot still sell because their assets are down big that they might think they already loss due to the big loss of value.
