From my life experience, solely a technical problem. The challenge is coming from the people around you. People around you, will ridicule you or brand you a smart person, busy, diligent, show off kepinteran, looking face etc .. They feel annoyed about working, feeling accused of postponing work, feeling they have to do the hard things.
Actually it's all a common assumption. To overcome it all, you must remain polite, calm, polite, not arrogant, speak good words, you must find out their weaknesses in work, you have to set an example, and the important thing is try to get their support.
