Yes it is true many times some things take extra time, but for that you will realize as you plan your time and activities, when you execute them as you really want to do them you will measure the time you need, for example to me to make some crafts for my posts take me two hours and I was stressed now I leave two hours for it in my time.
Before like you I only planned and didn't execute but it's a matter of doing it, so let's get to work and zero procrastinate 😉
