Do not listen to automatic recommendations say the long videos are not suitable. It is true that there is a majority of people perhaps yourself’re included- who like to be fast and not paying much attention.
Now or never
Success with bad short videos
Success with good long videos
Be a buisiness man project
I'll give you a key recommendation for this case: if you are in that group, get out of there immediately and strive to pay attention not only texts and short videos. That way you will learn much more than the rest. That said, now it will be important that you make good videos, not too long, not to lose the attention of the fools who always need everything to be short, because they are not trained to pay attention.
