Only if you are able and willing to be nice person who thinks of others 100% of the time. It takes time (countless reincarnations) to be a truly perfect nice person and by that time you would have already attained Buddhahood. If you’re keen in aiding suffering beings and gaining wisdom, you may proceed with Mahayana or Bodhisattva path to Buddhahood. Anyway, don’t be too hard to yourself for this matter, always be sincere and true to yourself and others.
