When we fear to take actions, we too often use the excuse of not knowing what to do.
Actions will generate responses. All you have to do is to adjust according to your plan and keep going on.
« Trust yourself, you know more than you think you do. »
– Benjamin Spock
If you don’t take action, you can’t get any responses and you can’t adjust. Without action, you don’t go anywhere.
Yes, you’ll make mistakes. Yes, you’ll take some wrong actions. But in the end, with your adjustment, you’ll get what you want (or something very close to it).
