Need some advice regarding part time work/freelance and pension

I been applying for jobs so far, and at the moment no luck on full time but maybe there's a chance at part time. I like to ask as I need to focus on 10 years of work to get a pension whether part time would contribute to that or do I need to look for a full time work?. I was thinking I speaking to a relative she feels I was seriously stupid for not freelancing and offering my skills in design. So not sure if that is another avenue I can also take, however, wouldn't mind doing part time and freelancing together as it help me getting out of the house and meeting people.
