Hexagram 8, Bǐ (Holding Together): Line 4
比卦六四 · 水地比 · 中文版
六四：外比之，贞吉。
The line (Legge)
In the fourth SIX, divided, we see its subject seeking for union with the one beyond himself. With firm correctness there will be good fortune.
Small Image commentary
'Union is sought (by the party intended here) with one beyond himself, and (in this case) with a worthy object:' - he is following (the ruler) above him.
象曰：外比于贤，以从上也。
In plain words
Drawing close outwardly; steadiness brings good fortune. The fourth line and the first are both yin and do not correspond, so it turns outward and draws close to the fifth line right beside it, serving a worthy ruler. The Small Image says drawing close to the worthy outside means following the one above.
Applying it to your situation
If there is no one around you worth learning from, this line suggests going outward to find someone worth following. Who would you most like to learn from?
Position
A broken (yin) line in the fourth place, which is a yin (even) place, so it is in its proper place. Its partner is line 1; both are yin, so they do not respond.
If this line moves
With this line moving alone, Bǐ changes into Hexagram 45 Cuì (Gathering Together). The Jiaoshi Yilin verse for this change (Chinese): 焦氏易林·比之萃.
The hexagram
Hexagram 8 Bǐ (Holding Together). The Judgment: Bi indicates that (under the conditions which it supposes) there is good fortune. But let (the principal party intended in it) re-examine himself, (as if) by divination, whether his virtue be great, unintermitting, and firm. If it be so, there will be no error. Those who have not rest will then come to him; and with those who are (too) late in coming it will be ill.
