We must discriminate between strong and weak Ascendant types. A strong type Aries Ascendant would be willful, forceful, outgoing, outspoken, headstrong with much drive and initiative. Strength of planets should be determined by sign, house and divisional positions, as well as by directional strength and by aspect. A planet can only give the results it indicates if it has the power to do so.
Elaborate calculations to determine exact planetary strength exist, as under Shadbala. Such calculations, however, tend to obscure the obvious. If, for example, the Moon is aspected by Mars, Saturn and Rahu and is weak in brightness, it will not likely give good results whatever its Shadbala or other strengths. So it is important to learn the obvious first and not to consider bewildering calculations which are only a matter of fine tuning.
There are no absolute rules of chart interpretation. All depends on our capacity to read the pattern of the chart according to the logic of how the main indicators function.
