Can somebody tell me why I shouldn't just pack it in? This is a question that we ask ourselves frequently along our life's journey and the answer is always the same..."you and only you can determine when you've had enough".
Now, my take is this, if you are asking the question, then you aren't ready to pack it in. Trust me, you'll know when to call it quits, if it comes to making that decision.
Dig deeper for patience.
Sit quietly, the answers will reveal themselves when you least expect them to. The past is gone, the present is a gift and you need to focus on today, allow the future to reveal itself when it is ready.
