Is there an existence of a single goal in life?

Argument one:
• Ends form either infinite regress or one final end
• If ends form infinite regress then our end is empty and vain
• Our ends are not empty and vain
• Our ends therefore don’t form infinite regress
• Conclusion: there is one final end

Argument two:
• Ends form either infinite regress, one final end or multiple ends
• Not infinite regress
• Not many final ends. If there were many final ends then we wouldn’t be able to choose, but we are able to choose
• Therefore there’s one final end

The one final end is HAPPINESS.
Is the one final goal happiness?
