Many new series never get out of the low tens for subscribers. If you have escaped from that hole, look for others out there who might need a helping hand. Even if you haven't received this kind of help on your journey, you can always give it to others to start the cycle. You can ask for mutual subscriptions and start collaborations, shout-outs, guest comic spots, and other things that might not only help them, but can encourage them to keep moving forward and do the same for other missed series.
