It’s important to make a new plan, when the old one is obsolete.
It’s easy to start making new plans when the old targets are getting out of reach.
It’s important to recognize a dip when you see one.
Now the decision is up to you.
Do you make a new plan, that’s even better, and go for it? And if yes, is this a pattern or an anomaly?
Or do you stick to the plan, overcome fear, overcome pain and overcome frustration by solving the complex puzzle the hard way: sitting down and making the time & energy investment necessary until it becomes easier?
No one said you need to do it on your own.
