When I was around 20 I had the privileged to attend a seminar hosted by Jim Rohn. At the time I didn’t understand how lucky I was. One of the take always from that seminar was the statement “Don’t wish it was easier, wish you where better”.
I don’t know how spiritual you are. But I can tell you that just as the body needs conditioning so does the spirit. Your spirit need to be beaten to submission and reforged to become stronger. This process will happen all through life, it will never end.
And why should it? Why should you ever stop growing? See each challenge as a trigger to grow. I understand that there will be moments that you feel like the weight of the world is on your shoulders, we’ve all been there. But never stop growing, never with it was easier.
