I made some edits to Seneca's 78th letter to Lucilius for you.
"Even if death is on its way for you, though it may come early, you have already experienced every gift that a very long life can offer. You gained extensive knowledge of the world we live. You learned that time adds nothing to the finer things in life. You've learned that life measured in pleasure and through the accumulation of desires must seem short and empty.
You are already everything you need to be complete."
The person you are now is the result of everything you have done up to this moment. You are exactly the person you are meant to be. You are complete.
If you want to know who you will become, start with thinking about the next thing you'll do after reading this sentence.
