In English there's an expression: _don't lose the forest for the trees_.

<div type="expander" caption="">
<table>
	<tr>
	<th style="text-align: center; background-color: #eeeeee">Forest</th>
	<th>&nbsp;</th>
	<th style="text-align: center; background-color: #eeeeee">Trees</th>
	</tr>
	<tr><td>&nbsp;</td></tr>
	<tr>
		<td style="text-align: center;">
        <img src="https://s3.amazonaws.com/mjs.neo.learning.images/MortonArboretumForest.jpg" width="400" />
		</td>
		<td>&nbsp;</td>
		<td style="text-align: center;">
<img src="https://s3.amazonaws.com/mjs.neo.learning.images/MortonArboretumTrees.jpg" width="400" />
		</td></tr>

<tr><td>&nbsp;</td></tr>
		<tr>
		<td style="text-align:center; font-size: 2.5em;"><i style="color: blue;">Ah, I see.</i></td>
		<td/>
		<td style="text-align:center; font-size: 2.5em;"><i style="color: blue;">I'm lost!</i></td>
		</tr>
	</table></div>


For now, just focus on high-level concepts, and don't worry about the details.
