There are several ways to minimize distractions during your working hours. One of the best ways to reduce distractions is to choose a designated workspace and stick with it. A full home office with a door is best to physically block distractions like spouses, kids, TVs, and the like.
However, if you don't have that option, choose a designated space and communicate to family members that you're off limits when in that space.
Putting your phone away from you is another great way to ditch the distractions. Even if you don't look at it, even just hearing your phone can be enough to steal your focus. So turning it off or leaving it in another room are the best ways to eliminate the temptation to look at it.
