Please help my plan my 20s out

I have an early idea for what I'm going to be doing for the next 5~ years, but no clue on what I'll be doing after. I'm currently 21 with 8k in savings. I plan to have 25-30k by 25 to use as a down payment on a house. After that, I'm not sure what I should really do, probably save $5k for a savings account just in case account, but no idea besides that. I plan on graduating college by 23 and hopefully making more by that point.

I really would like to save a bunch of money after my house, so I want at least $50k by 30, but not sure exactly what I should do with money I work on saving.

What would you think is the best idea for a general 10~ year plan?
