Internal Distractions comes from inside of yourself, generated from our own self image and perceptions. When we are disturbed due to thoughts or due to the inner self perceptions, this is defined as Internal Distractions. Internal Distractions are caused primarily from the unruly Negative Ego, it is when self love and self acceptance is not present, and there are things that the you want to change in yourself or the mind wants to gain control to change others. This inner struggle produces frustration from inner conflicts stemming from your own thoughts.
External distraction are easier to overcome, while it takes mental discipline to overcome internal distractions, as it involves gaining control over your mind. 
Distractions can come from both external sources and internal sources. The motivation of someone intentionally creating external distractions is that they generate an assembly line of interference, which disables their ability to focus their attention on meaningful, accurate and truthful things. When people are unable to focus their attention, they effectively have attention deficit and scatter themselves. Thus, it is much harder for them to manifest anything meaningful to their spirit that requires a deeper concentration of focusing ones energy and intention. External distractions may include a variety of factors such as internet click bait, social media, phone or text messages, emotional dramas, substance abuse, porn, and fear based media and television shows. There are also Internal Distractions, which are mostly caused by the unruly Negative Ego’s survival fears such as anxiety, worrying, obsessions, and fantasizing.
