Welcome to the greatest, most frustrating, most rewarding sport there is!
However, for most golfers the word "consistency" is an oxymoron.
This game requires a great amount of patience and discipline...and please, don't be too hard on yourself if you play well one day and struggle the next. That's golf. Even the pros can have 10 shot swings from one day to the next.
Go with what you've got and do your best. You can't ask anymore from yourself.
And again, welcome to golf!
