HELP!!! Overly Timid gyp

I had a dog that was timid as hell I eventually broke him of it but it took a lot of time on my part every night at feed time I'd get in his pen and sit down and just hang out look at my phone or whatever I never paid him any mind until he came to me then I'd pat him on the head a time or two and go back to ignoring him.After he'd come and give me a sniff and let me touch him once or twice I'd feed him.On my days off I'd go out to his pen a few times a day and do this when it wasn't feed time I'd give him some sort of treat piece of hot dog or something but only after he let me touch him.eventually he was trying to sit in my lap when I would go in there with him.I never was intimidating to him just let him do all the work.
