I am 27 and feel like I do not have time left to invest and missed out on tech being cheap!

Hello all, I feel like at being 27 I have missed out on the lows of dec and tech has been in a bull YTD. Similar to 2020, that being said I can invest in other stuff that isnt moving like DIS or a different sector. Keep at it over time and build wealth. Should I save a lump sum and buy or DCA my way into the market? Also, I feel like I have no time left at 27
