To be careless in making decisions is to naively believe that a single decision impacts nothing more than that single decision, for a single decision can spawn a thousand others that were entirely unnecessary or it can bring peace to a thousand places we never knew existed.
At the critical juncture in all human relationships, there is only one question: What would love do now? No other question is relevant, no other question is meaningful, no other question has any importance to your soul.
At the end of the day, it’s your life. If you turn out good, the world celebrates you and with you (not minding how you achieved it). If bad, they abandon you (even if they gave you the advice that led you to doom). Just be you and follow your heart.
