The best way I've found is using Discord communities and just finding some good and popular steemians and commenting their posts, adding value to them. Every day.
It takes time and inolvement. Discipline. Post and comment everyday. At first its frustrating, but in time it slowly starts to add on. I have now 200 SP in three months (After losing about 50 in bots and frauds). I post twice almost every day and comment about one or two hours every day. Other thing you can do is participate in giveaways and contests.
These are good, active discord groups you can try (They are general communities, there are also specific groups for literature, art, science, education, crypto, etc.)
Sign up to a few. Socialize. Make yourself available.

Just remember: DO NOT BEG FOR UPVOTES. It is like a capital sin here.
Good luck.
