You are welcome!
"Ela olevikus! Ehita tulevikku!" is imperative mood:
Live in the present! Build the future!
If you want imperative, then maybe even more fitting would be "we"-imperative:
"Elagem olevikus! Ehitagem tulevikku!"
~ (Let's) live in the present! (Let's) build the future!
I can manage,
trying to learn,
