For me, blocking out time helps.
And if it's not urgent, getting comfortable with the task sitting there helps!
A friend of mine recently said something to me that shifted how I view my lists: Having empty lists would mean that nothing is going on in your life.
After that, getting comfortable with stuff sitting there for some time helped me a lot.
Sure, stuff might grow stale, but only if I don't do my Weekly Review, where I have the chance of renegotiating the commitment with myself. I can always move it to someday/maybe, tickle it or drop it completely.
And if it is something I really want to do, but I never seem to get to that particular context, I just give myself the gift of blocking it into my calendar.
Another strategy that I used recently was chunking it down. Me and my spouse just moved and we procrastinated on getting our cellar organized. After a few weeks of feeling guilty about it, I said "Hey, when I come home from work on tuesday, let's just meet down there and work on it for just 15 minutes. Even if we don't get much done, just being there might give us an idea of how to move forward some other time." ... When the day came, we organized the whole cellar, lol.
