TQQQ worth it as market is in a decent dip?

Is TQQQ worth having some exposure to with the market being down a good amount?

Have stable income,age 23, so have long time horizon(30-40 years).

Currently just finished adding the last $2650 to my Roth IRA(HSA has been maxed since earlier thus year) and am debating putting it into FSKAX/FTIHX(75/25) like I have been doing,or maybe adding some into TQQQ for quick boost in gains once the market recovers.

Thoughts?
