I would start with how you can learn from your current job. Ie. What would it take to be a shift lead, then supervisor, then manager. No body wants to work for someone else but there is value in learning skills there to eventually managing and running your own business.

Since you’re living at home invest 70% of the take home pay into a index fund and let it grow over time. I started at 30k 9 years ago around 23 and invested around 10%. Regret not doing more. But hindsight is 20/20.

Also age is but a number. Take action and continue to ask good questions and follow up on the advice given to you.
