Here is a straightforward look at this topic for Malachain.
Vague requests get vague answers. "Can you help me with the report?" invites a sigh; "Could you check the two figures on page three before four o'clock?" gets done. Say exactly what you need, by when, and why it matters, and make it easy to say yes by keeping the request small and the deadline reasonable.
Ask in person or by voice for anything important, and follow up with a short written note so nothing is forgotten. Thank people specifically for what they did, not generically. Over time, being the person who asks clearly and thanks properly makes others far more willing to help the next time, and it quietly improves how you explain things in general.
The most useful step is usually the first one. Pick a single suggestion, try it for a couple of weeks, and then decide whether it is worth keeping. Small, steady improvements last longer than ambitious plans that are hard to maintain once everyday life gets busy again.
It also helps to talk the subject through with friends or colleagues who have tried something similar. Their experience points out the details that guides leave out: how long things really take, which costs were unexpected, and which shortcuts turned out to be a mistake.
There is more to learn on this subject, and the linked website goes into greater depth. Treat this article as an introduction rather than the final word, and check any important decision against up-to-date, reliable sources before relying on it.
If you try any of these ideas, start small and adjust them to your own situation. What works for one person will not suit everyone, and it is fine to keep only the parts that help. Writing down what you changed, and what happened, makes it much easier to see after a few weeks whether the effort was worthwhile.
