One of the strengths of the Theravada tradition is the practicality of the Eightfold Path. You are given a concrete list of instructions for how to form your soul.
You want to experience less interpersonal suffering? Speak in a way that is kind, gentle, and brings unity.
You want to be at peace about how you earn your living in this world? Don’t profit off of what hurts other beings.
You want to harbor less anger? Develop the intention of lovingkindness toward all life.
Whether or not one thinks the Eightfold Path is the way to end suffering or some kind of absolute spiritual path, it at least provides a concrete, practical framework for how to develop yourself toward the Good. Following it can lead to less suffering, in practical ways.
