There's nothing wrong with working a 9 to 5 job if that's what pays your bill. People who talk down on people who work a 9 to 5 or multiple jobs are probably jobless or just critics. Life is in phases, not everyone is going to figure it out easily. If working this type of job is a start for you there's absolutely nothing to be ashamed of, all you need to do is plan for a better future, save up to start up your own business because being self employed is one of the ways to facilitate success. As long as you are not planning to do such a job forever then there's nothing wrong about it.
Everyone must do a job to be able to earn an income to be able to meet their needs and whatever job they do is certainly what they feel comfortable doing as long as they can get an income that can meet their needs and if there are some people who look down on other people's work, of course they are not workers and it can be said that they are only good at correcting other people's work but they themselves do nothing, of course that is very stupid.
I agree with you, there is nothing to be ashamed of doing a 9 to 5 job and if we have a good plan for the future like trying to learn a skill that we can do anytime or trying to save as you said is also possible and when we have enough savings to start a business, of course we have studied it well so that we can run the business well.
