Have you looked up the definition of the two most important words in the phrase ("stick (to)" and "convictions")?
Remember to put words and phrases that you are querying inside quotation marks (or italicise them, or make them a different colour) so that they stand out from the rest of the sentence.
Congratulations. That is correct. When you find a phrase that you don't know in future, look up the relevant words, try to work out the definition, post the phrase and what you think it means here, and we can help you. That is much more educational for you than simply asking us what something means.
