Don’t put too much pressure on yourself, do the best you can in the time you have but remember to try experiments of posting at different times to test out different types of content and the reaction they get.
Be deliberate about what time you post, keep them the same for a week, then the next week change by a new time and keep for that week.
When you are thinking about the time of post, put yourself in the shoes of your audience and think when would be the highest time that they would be likely to convert to my call to action and start experimenting with those times and monitor the result. Don't be afraid to try new things with the time to post, just keep consistent with how you do it.
