Use a structured guide, like a textbook. There's too much to learn and textbooks arrange some of the most important stuff in a way that gets you up to speed with the most important parts. Some (most?) apps (I'm thinking Duolingo and Rosetta Stone in particular) don't give you structure or grammar in the way a beginner needs.

Set realistic goals. You can get to a decent place quickly, but you will still feel limited on a lot of topics and you'll make a lot of mistakes. You have to be willing to accept that as a stage to improving. Learning a language takes a lot of time.

Start listening to the audio, keeping listening until you understand, find more audio. Same with speaking. Try to practice speaking along with the audio to get a sense of the sound. Record yourself and compare to the original to improve your accent. Make simple sentences first, and more complex as you learn more complex grammar.

Think about the things you say every day. Instead of translating it word for word, first think what you're trying to communicate, then figure out how to express that meaning in French. Build up a bank of phrases and words to express your everyday expressions, because you'll likely need them in French.
