A bit of a newbie myself. That bit of advice is right on the mark for me. ThanksAnother bit of advice...
Don't watch too many different videos by different people...pick one method and stick with it...
When starting out trying to switch between too many different techniques will slow your progress. Once you're able to get consistently repeatable results then experiment all you care too.
And remember, when starting out as long as it's sharper than when you started...it's a success... you'll soon enough get to whatever standard you feel is sharp enough....
Take care
