Planning the Story

So recently I have been going through all my chapters and trying to figure out what was the best way to write this story. I am debating with myself on either doing a time skip to when the action starts with brief descriptions of what the MC did over the years. Or do the next few chapters continuing as I have but focusing on major points and events. I am leaning more towards the time skip but feel it wouldn't do the story justice and will lead to many flashbacks.
