We all replay old messages; those that tell us what we "should" do. Whose "shoulds" are you hearing? If they are those of your own conscience, go ahead and follow them. If they are outdated "shoulds" from parents, siblings, spouses, teachers or others, proceed with caution.
Acting on the values of others makes us disingenuous people. Eventually, our selves splinter. We become disenchanted, depressed, not "ourselves." When we integrate all the parts that make us unique, we are whole, content, and happy.
When you follow your heart, you become genuine. When you are whole, you have reserves to weather life's challenges, energy to give to others, and the ability to appreciate the love that comes your way.
Follow your heart.
