I teach people certain habits to use in their work. The benefits are often a bit delayed. This leads them to wonder when they will benefit and to doubt whether they're doing it right.
Let me offer this observation: you probably care less about doing it right than you care about whether to keep trying.
Is that so? Maybe yes, maybe no.
Either way, I encourage you to clarify this in your mind, because different strategies help in each of those two mind states.
