It’s okay to make changes to what you planned
One of my biggest pet peeves is when people get their panties in a wad when thing don’t go perfectly to plan. For some reason they think that if it doesn’t happen the way they planned, it’s not going to work at all. But that simply isn’t true.
Even the best football teams and quarterbacks call audibles.
Don’t be afraid from deviating from the plan if it is need. What you change to might work better in the end.
